It’s like scientists have a word for everything—even all those strange, disgusting, embarrassing, and perplexing things your body does totally on its own. Here are all the technical names for the things you have to apologize for doing.

1. Food coma.

It’s the most first world of all first world problems: eating so much food in one sitting that you get sleepy afterward. A food coma is most strongly associated with Thanksgiving, and for decades the myth persisted that a chemical in turkey called tryptophan caused sleepiness. It doesn’t—eating a ton of calories makes the body slow down considerably, no matter if it’s a big lunch or a whole thing of cupcakes. The name for food-induced sleepy times: postprandial somnolence.
